Daniel Craig and Rachel Weisz Pack on the PDA at BAFTA Britannia Awards

Daniel Craig and Rachel Weisz have been famously tight-lipped about their yearlong marriage -- even the wedding was a secret -- but they couldn't hide their love at the BAFTA Britannia Awards in Beverly Hills on Nov. 7.

The usually super-private pair put on quite a public display of affection in front of their fellow awards show attendees, a source told Us of the "so in love" stars.

"They were both very smiley and happy-looking. Rachel was in a jubilant mood," the onlooker said, adding that the couple laughed "uproariously" throughout the evening and "[couldn't] stop touching" each other. "[Daniel] kept his hand in Rachel's lap the entire time and would lean in to kiss her now and again. He was also rubbing her back and stroking her thigh."

The James Bond portrayer, 44 -- whose latest 007 film, Skyfall, is out Nov. 9 -- began dating his Dream House costar, 42, in December 2010, shortly after both got out of long-term relationships. (Craig romanced film producer Satsuki Mitchell from 2004 to 2010; Weisz dated director Darren Aronofsky, with whom she has a 6-year-old son, Henry, from 2001 to 2010.)

Six months later, in June 2011, the two wed in a secret ceremony in upstate New York. Neither has spoken much about the relationship since then, but their hands-on appearance at the BAFTA Awards spoke volumes -- as did Weisz's endorsement of Skyfall.
